- added check for empty file name as the export doesn't work without one:
`[Error] Argument 1 passed to Friendica\Moderation\DomainPatternBlocklist::exportToFile() must be of the type string, null given, called in /var/www/.../src/Console/ServerBlock.php on line 110`
{
$filename = $this->getArgument(1);
+ if (empty($filename)) {
+ $this->out('A file name is required, e.g. ./bin/console serverblock export backup.csv');
+ return 1;
+ }
+
$this->blocklist->exportToFile($filename);
// Success
